relationships Flashcards
sexual selection
Characteristics passed on for reproductive advantage not survival
Any genes that promote successful reproduction are selected
Anisogamy
difference between male and female sex cells
Plenty of sperm - ‘cheap’ but ova are ‘expensive’ because they require more energy to produce them and there’s a limited amount
consequence of anisogamy
lots of fertile males=quantity over quality
less fertile females=quality over quantity
This gives rise to 2 different mating strategies inter and intra sexual selection
Intra- sexual selection
Selection of mates within sexes, eg males competing with each other for a female. Males who win pass on genes
what patterns of behaviour do intra-sexual selection pressures lead to
Physical consequences - males who are bigger win competitions for mates
Behavioural consequences - male aggressiveness also helps competitions
Inter-sexual selection
One sex evolves preferences for desirable qualities in mates which gives an advantage to those genes
(females select males/ males select females)
Females (quality over quantity)
females more committed - therefore the females mating strategy is to select a genetically fit partner who is able to provide resources
Buss
10k pps from 37 different cultures and found universal traits. Women desire resources and intelligence and men desire youth and attraction
inter-sexual selection impact on partner preferences
female preferences determine features passed on in offspring
disadvantages of evolutionary explanation
-Mate choices vary during menstrual cycle
-Women have desire to be breadwinner
-Cultural traditions impact mate preference
self-disclosure
Disclosure about personal disappointments, accomplishments and sexual relationships have a greater influence on relationship satisfaction
social penetration theory
reciprocal exchanges of information between partners that is gradual
what does social penetration lead to
development, penetrate into each other’s lives through the sharing of info
what is info like at the start of social penetration
Breadth is narrow because if too much info is revealed too soon it can be off putting and one partner may to decide to quit the relationship
what happens to the info shared as more time goes on in social penetration
Depth increases, likely to reveal more intimate info as time goes on like personal memories
Reciprocity of self disclosure
Reis and Shaver suggest that there must be reciprocity alongside the broadening and deepening of self-disclosure
strength of self disclosure
+Important for developing and maintaining relationships
+’boom and bust’- more likely to disclose online
+TV viewers prefer reality stars who gradually disclose
+disclosure stronger face to face then online
weakness of self-disclosure
-Cultural differences between Western and non Western and genders
-Deterministic
physical attractiveness
how appealing a persons face is, agreement across cultures of what makes someone attractive and assumption to form relationship with attractive person
symmetrical faces
people with more symmetrical faces are more attractive as it is a sign of genetical attractiveness that cannot be faked
Evolutionary basis
physical attractiveness indicated natural selection
Baby face features are seen as attractive because because they trigger protective and caring instincts
The Halo effect
people have preconceived personality traits they think attractive people have
Dion et al halo effect
found that physically attractive people are consistently rated as kind, strong , sociable and successful compared to unattractive people
matching hypothesis
We seek partners whose social desirability matches our own
Walster matching hypothesis
Computer dance- matches PPs on physical attractiveness, intelligence and personality. PPs likely to arrange further date if they deemed them attractive
EASTWICK
Speed dating research found that PPs did not match on pre chosen physical characteristics but personality
physical attractiveness strength
+Real life application to understanding initial attraction in relationships
+Husbands who viewed their wives as attractive had higher satisfaction
physical attractiveness limitation
-People may settle with unattractive mates due to other desirable traits
-Online dating is based on the whole package not just attractiveness
